Program to find largest and smallest among 5 numbers without using array

Question

Yesterday I went for an interview where I have been asked to create a program to find largest and smallest among 5 numbers without using array.

I know how to create

Answer 1

Heres what I did, without using an array. This was a method to return the highest number of 5 scores.

double findHighest(double score1, double score2, double score3, double score4, double score5)
 {
   double highest = score1;
   if (score2 > score1 && score2 > score3 && score2 > score4 && score2 > score5)
      highest = score2;
   if(score3 > score1 && score3 > score2 && score3 > score4 && score3 > score5)
      highest = score3;
   if(score4 > score1 && score4 > score2 && score4 > score3 && score4 > score5)
      highest = score4;
   if (score5 > score1 && score5 > score2 && score5 > score3 && score5 > score4)
      highest = score5;
   return highest;
 }

An array is going to be far more efficient, but I had to do it for homework without using an array.
